Embodiment two
As illustrated in figs. 5-7, in the present embodiment, it is preferred that also include that pipeline stable-pressure device, described pipeline stable-pressure device are arranged on
On well water water inlet pipe, described pipeline stable-pressure device connects well water heat exchanger by way flow taps.
Described pipeline stable-pressure device includes voltage stabilizing valve plate, bolt head and several annular liquid capsules, the lower end of described voltage stabilizing valve plate
Insert in well water water inlet pipe, the upper end coupling bar head of voltage stabilizing valve plate, described annular liquid cuff be contained in well water water inlet pipe and bolt head it
Between voltage stabilizing valve plate on；Described annular liquid capsule from bottom to top includes the first liquid capsule, the second liquid capsule, the 3rd liquid capsule ..., N liquid
Capsule.Described first liquid capsule, the second liquid capsule, the 3rd liquid capsule ..., N liquid capsule respectively by the first drainage tube, the second drainage tube,
3rd drainage tube ..., N drainage tube connect the A point on well water water inlet pipe, B point, C point ..., A point, B point, C point ...
From well water pump distance gradually away from；A point, B point, the liquid stream of C point ... enter different annular liquid capsules by drainage tube, according to well
The degrees of expansion of the pump outlet capacity regulation annular liquid capsule of water pump, order annular liquid capsule expands jack-up voltage stabilizing valve plate；By voltage stabilizing valve plate
Hoisting depth control the water-flowing amount in well water water inlet pipe, make the hydraulic pressure in well water water inlet pipe keep stable.
Described pipeline stable-pressure device connects unimodal current by elastic expansion pipe and switchs.
Described pipeline stable-pressure device is provided simultaneously with two functions: the first, pipeline stable-pressure device can be by detection annular liquid
Bulge number and the degree of capsule are to judge the pump outlet capacity of water pump, thus judge the ability to work of water pump, control water pump in time
Performance degradation speed and degree, convenient maintenance in time or replacing.The second, annular liquid capsule is regulated by the pump outlet capacity of well water pump
Degrees of expansion, order annular liquid capsule expands jack-up voltage stabilizing valve plate；Controlled in well water water inlet pipe by the hoisting depth of voltage stabilizing valve plate
Water-flowing amount, makes the hydraulic pressure in well water water inlet pipe keep stable.Described pipeline stable-pressure device connects unidirectional water by elastic expansion pipe
Stream switch, when the hydraulic pressure in pipeline is little, elastic expansion pipe shrinks, and makes water flowing diameter diminish, thus keeps the pressure of current；Instead
It, elastic expansion pipe swells, and makes water flowing diameter become big, prevents that descaling line pressure is excessive to cause damage to tube wall and well water heat exchange water device.
Remaining structure, with embodiment one, repeats no more.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees other form, appoints
What those skilled in the art is combined possibly also with the technology contents of the disclosure above, changes or retrofits and is the present invention
Equivalent embodiments.But every without departing from technical solution of the present invention content, implement above according to the technical spirit of the present invention
Any simple modification, equivalent variations and the remodeling that example is made, still falls within the protection domain of technical solution of the present invention.
